UNITED STATES PATENT GEErcE.

ISAAC H. ADAMS, OF MONTANA, IOWA.

Specification forming part of Letters Patent No. 117,499, dated August1,1871.

To all 'whom t may concern:

Be it known that I, IsAAC H. ADAMS, of Montana, in the county of Booneand State of Iowa, have invented a new and Improved Washing- `Machine;and I do hereby declare that the following is a full, clear, and exactdescription thereof, which will enable others skilled in the art to makeand use the same, reference being had to the accompanying drawingforming part of this specification.

This invention relates to a new and improved washingmachine, in whichthe essential feature is an arrangement of the rubbing-boards, which isplaced in the bottom of the tub, and commonly made stationary7 with ajoint at or about the center, and connecting the lower part with thelevers for working the vibrating' board, so that after the latter hasbeen raised well off the clothes the said jointed part will be raised soas to turn and shift the clothes to facilitate the presenting all sidesto the rubbing-boards.

Figure lis a sectional elevation of my improved machine, and Fig. 2 is aplan view of the same.

Similar letters of reference indicate corresponding parts.

A is the case or tub, which has three vertical sides and one obliqueside, B, 011 which, near the bottom, is placed a iixed rubbing-board, C,and below this and over the bottom of the case is another rubbing-board,D, which is hinged to the lower edge of C, as shown at E. This part hascurved bars, F, jointed to it, one at each end, which arms have a slot,G, in the upper part, by which they are connected to the bars H, bywhich the movable rubber I is connected to the handlevers K for beingvibrated, each bar having a stud-pin, L, for working in the slot of thebar connected to it. The movable rubbing-board is rigidly connected tothe bars H, and it has a stud-pin, M, with friction-rollers, one at eachend, projecting into a curved guide-slot, N, -in each end wall of thetub for guiding the said board in its up-and-down movements on theclothes, which are placed between it and the lower board C D. Orepresents a hand rubbing-board applied to the inner wall of the obliqueside B of the case in a convenient position for use when any handrubbing is required. The said board may be formed by working groovesinto the board B, or a corrugated or grooved board made separately maybeattached. The rubbing-boards O D and M have slots P made through them,as shown, to facilitate the circulation of the water. The rubbing-boardI may be worked over the one O D, the same as would be the case if thelatter were one rigid board, as they are commonly arranged, by notlifting the levers K high enough to raise the bars F, but by raisingthem higher, so that the stud-pins I coming against the upper walls ofthe slots will lift the part D of the lower board and swing it on thejoint E, it will turn or raise the clothes and present them to the upperrubber in a new position to be acted on by it; and, also, the saidrubber I will shift the clothes so presented, or act in conjunction withthe lower rubber C D for shifting them.

Having thus described my invention, I claim as new and desire to secureby Letters Patentl. The combination, with the movable rubbingboard I, ofthe board C D, the latter being made in two parts, one of which ispermanently attached to the tub and the other hinged to the first, andarranged to work in conjunction with the board I, all substantially asspeciiied.

2. The part D of the lower board, connected to the bars H of the boa-rdI by the curved slotted arms F and studs M, all substantially asspecied.

3. The board I, having the studs M arranged in the curved grooves N inthe ends yof the tubs, all substantially as specied.

ISAAC H. ADAMS.
